Disklavier

I went ahead and uploaded the program I mentioned.  It's in the Files area of this group.  File name: FMT.zip.  It allows formatting of disks of many different sizes, including 720k.  I've been successful in formating "taped-over" 1.44k disks as 720k disks using Windows XP.  For it to be successful, I've first formatted the disk in my MX85, then use this program to format 720k.  Then I've moved .fil files onto the disk, and used dkvutils to create and populate the pianodir.fil file.  I have also successfully used the CONVERT funtion on the MX85 without using dkvutils.
